Answer:
Step-by-step explanation:
Before you add 2 fractions, the denominator needs to be the same. If they are the same, which they are, then add the 2 numerators.
1 plus 2 equals 3.
So the answer is 3 over 5.
The square numbers of 45?
I don't really know what you mean by that but if you're looking for the square numbers before 45, they are as follows:
1
2
4
9
16
25
36
Hope this helps :)
The two numbers are very near 7200 and 300. The sum of those is a good estimate of your sum:
... 7200 + 300 = 7500
_____
If you're taught methods of addition that include "make a ten" or "make a hundred", you know you can "borrow" a 1 from 7203 (making it 7202) and loan that 1 to 299 to make it 300. Now, you know your sum is exactly 7202+300 = 7502, with no estimation necessary.

Answer:
∠ B = 53°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles from 180 for B
∠ B = 180° - (90 + 37)° = 180° - 127° = 53°
